China’s stone resource reserves are the largest in the world, and its consumption is also the largest in the world. Its dense structure makes it one of the earliest building materials in human history. It is also recognized as a good material in the construction industry because of its “long history + outstanding performance + wide range of applications”. This issue will introduce in detail: Granite.

Natural Stone High Polished Blue Bahia Granite Quarzite

ONE Formation of granite

Granite is a magmatic rock (igneous rock) formed by magma. In the process of underground magma rising to the weak part of the crust, part of it flows out of the surface.
Another part of the magma is lazy. The high temperature melts the surrounding rocks and does not want to go, so it condenses in the rock layer. Granite is formed by the condensation of this kind of magma that invades deep underground. Because it is under high pressure in the underground rock layer, the texture is hard and not easy to corrode.
When the crust moves up, the rocks covering it are weathered and peeled off, and the granite can no longer be hidden and exposed to the surface. my country’s (Mount Tai, Mount Huang, Mount Hua, etc.) are all granite mountains.

TWO quality performance

Granite is mainly composed of quartz, feldspar and mica, of which feldspar content is 40%~60% and quartz content is 20%~40%. Its color depends on the type and quantity of the components. Granite is a rock with a fully crystalline structure. High-quality granite has fine and uniform grains, compact structure, high quartz content, and bright feldspar luster.
Granite condenses below the surface. It has a hard texture and is not easily weathered or corroded. It is an ideal material for producing wall tiles and floor paving.
Granite is the hardest building material, and its super hardness also makes it very wear-resistant. Granite is stronger than sandstone, limestone and marble, so it is more difficult to mine. Granite is a unique material, and its physical characteristics give it the following properties:
#01 High waste rate and good wear resistance: It has excellent processing performance and good splicing properties;
#02 Bright colors and solemnity: It has good decorative properties and is suitable for public places and outdoor decoration;
#03 Good performance: It is non-conductive, non-magnetic, stable in field, large elastic modulus, higher than cast iron, good rigidity, large internal damping coefficient, 15 times larger than steel, and can prevent and reduce shock;
#04 Stable chemical properties: It is not easy to weather, and its chemical properties are proportional to the content of silica, and its service life can reach about 200 years.
Because of these excellent properties, granite has become an ideal ceiling for the production of floor paving. It is more precious than most artificial materials, which also makes its value continue to rise.

THREE product classification

Granite resources are rich and varied, and it has been widely used in civil engineering since ancient times. There are more than 100 varieties of natural granite in China, and the production areas are mainly concentrated in Sichuan, Shandong, Guangxi, Fujian, Shanxi, Henan and Inner Mongolia.
The texture of granite is uniform. Although the color is mainly light, it is also very rich. It can be divided into the following color series:

Red series
Sichuan red, asbestos red, Cenxi red, tiger skin red, cherry red, Pinggu red, azalea red, rose red, imperial concubine red, Luqing red, Lianzhou red, etc.

Yellow-red series
Cenxi orange red, Dongliu meat red, Lianzhou light red, Xingyang peach red, Xingyang orange red, light red small flowers, cherry red, coral flower, tiger skin yellow, etc.

FOUR flower white series
White stone flower, white tiger stream, black and white flower, sesame white, flower white, Lingnan flower white, Jinan flower white, Sichuan flower white, etc.

Black series
Light blue black, pure black, sesame black, Sichuan black, Yantai black, Shenyang black, Changchun black, etc.

Cyan series
Sesame green, rice green, fine hemp green, Jinan green, bamboo leaf green, chrysanthemum green, blue and white, reed flower green, Nanxiong green, Panxilan, etc.
Imported granite
Golden diamond, South African red, fantasy green, Kashmir gold, small emerald red, dark green hemp, American gray hemp, fantasy red, Indian red, British brown, etc.

Iron Red Granite

Granite has become an ideal material in the field of construction and decoration due to its excellent physical and chemical properties. Its hardness, wear resistance, rich colors, and strong stability not only make it popular in the domestic and foreign markets, but also highlight its important position and application value in building materials. With the advancement of science and technology and design innovation, the application scope of granite will be wider, and it will continue to play its unique charm and role in the field of architectural decoration.
